Jacksonville Port Authority (Jaxport) said that the two LNG storage tanks for Crowley Maritime’s shore-side bunkering facility on Talleyrand Marine Terminal have been set on their foundations.

The tanks arrived at Talleyrand aboard the BBC Chartering vessel, Moonstone, from Hamburg, Germany. Each of the two tanks weighing 260 tons has the capacity to hold 1 million liters of liquefied natural gas and have been built by Chart Industries in Europe.

The facility, being built in cooperation between Crowley Maritime, Eagle LNG and Jaxport, will serve Crowley’s new Commitment class, LNG-powered, combination container/Roll-on Roll-off (ConRo) ships, which are under construction at the VT Halter Marine in Pascagoula, Mississippi, for use in the U.S. mainland-Puerto Rico trade.

The first of the two LNG-fueled vessels, the El Coquí was launched at the VT Halter Marine shipyard last month.

The vessel, like her sister ship Taíno, will be able to transport up to 2,400 twenty-foot-equivalent container units (TEUs) and a mix of nearly 400 cars and larger vehicles in the Ro/Ro decks.

The El Coquí is set to begin service in the second half of 2017 and with the second vessel expected to start service in the first half of 2018, according to Crowley Maritime.
